8 Dec 2017 04:01 - +14 What kind of sorcery is this?

8 Dec 2017 08:12 - +11 How much do these go for?

8 Dec 2017 09:06 - +9 I can't see a hydrofoil without thinking of the boat from Jonny Quest.

8 Dec 2017 09:44 - +7 I'm 250lbs, would this still work?

8 Dec 2017 10:02 - +7 Wow. I thought it was 2 separate boats - a yellow one and a white one - until it turned towards the camera. My mind momentarily melted.

8 Dec 2017 10:08 - +5 it's a pedal boat not a Paddleboat

8 Dec 2017 09:53 - +5 I want someone to make a green scaly hand to go around the "stalk" part so it's like a sea monster is carrying them around

8 Dec 2017 10:27 - +4 Okay Engineers, I have good news and bad news.
The good news is you will receive A's on this project.
The bad news is this will not help you get laid.

8 Dec 2017 07:11 - +2 I thought it said fail and was waiting for the flip

8 Dec 2017 08:42 - +2 Weeeeeee

8 Dec 2017 10:08 - +2 But why?

8 Dec 2017 11:45 - +1 For some reason I read paddleboat hydroplane and I just picture a guy with gigantic legs peddling so fast the boat is skidding on top of the water.

The video owner commented, "You can't buy one because it's a prototype ! but evolution are in development !﻿"
This is an awesome example of a hydrofoil.
Under the water effectively is a wing, it behaves in the same way as a plane wing. Often these can have their angle of attack adjusted too but it's unclear if the boat in the video can do that.
There's a sweet spot where the extra energy being spent creating lift with this wing is less than the energy saved by having less drag (once the boat is out of the water there's only a very small part of the boat submerged creating drag, which makes hydroplanes not only awesome to watch but quite efficient.
